[0022] The technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] A rubber product preform material processing device comprises a plunger 1, a material chamber 2, a base 3 and a discharge head 4; the middle part of the base 3 is sealed and plugged with the discharge head 4, the upper end of the base 3 is sealed and plugged with the material chamber 2, the upper end of the material chamber 2 is sealed and plugged with the plunger 1, and the discharge end of the material chamber 2 is connected to the feed end of the discharge head 4.

[0024] The plunger 1 includes a column head 1-2 and a top plate 1-3, and the column head 1-2 is integrally formed and coaxially fixed on the lower surface of the top plate 1-3.

[0025] The upper surface of the top plate 1-3 is evenly distributed along its circumference with multiple threaded holes 1-1 that penetrate its thickness direction. Considering that rubber has a certain viscosity, when the plunger 1 cannot be removed normally from the material chamber 2, the plunger 1 is removed by utilizing the reaction force of the screws in the threaded holes 1-1.

[0026] The material chamber 2 includes a barrel 2-1 and a material chamber ring plate 2-2. The material chamber ring plate 2-2 is integrally formed and coaxially fixed to the lower end of the barrel 2-1, and the cavity of the material chamber ring plate 2-2 is connected to the cavity of the barrel 2-1. A column head 1-2 is sealed and inserted in the barrel 2-1, and the height of the column head 1-2 is greater than the depth of the barrel 2-1 to ensure that all the rubber material can be squeezed out.

[0027] The base 3 includes an annular plug plate 3-1 and an annular bottom plate 3-2. The annular plug plate 3-1 is integrally formed and coaxially fixed to the upper end of the annular bottom plate 3-2, and the cavity of the annular plug plate 3-1 is connected to the cavity of the annular bottom plate 3-2; the annular plug plate 3-1 is sealed and plugged with the material chamber ring plate 2-2.

[0028] The discharge head 4 includes a accommodating cylinder 4-1 and an extrusion plate 4-3. The accommodating cylinder 4-1 is integrally formed and coaxially fixed to the upper end of the extrusion plate 4-3. An extrusion channel 4-2 is provided in the middle of the extrusion plate 4-3 through the thickness of the plate. The extrusion channel 4-2 is connected to the accommodating cavity of the accommodating cylinder 4-1, and the accommodating cavity is connected to the cavity of the cylinder body 2-1.

[0029] The extrusion channel 4-2 is the final size of the preform, and the size of the extrusion channel 4-2 can be designed according to the required size of the product, that is, only the material head 4 needs to be replaced each time to realize the processing of preforms of different products.

[0030] The accommodating cavity is an inverted frustum-shaped structure that is wide at the top and narrow at the bottom, which facilitates the flow of the rubber material.

[0031] When the utility model is used, the rubber raw material is placed in the cavity of the cylinder 2-1, and the rubber is squeezed under the action of the column head 1-2. The rubber flows through the accommodating cavity of the discharge head 4 and is extruded through the extrusion channel 4-2 to complete the processing of the rubber product preform.
